{% switch %}

This tag provides switch statement functionality to your templates.

“Switch statements” offer a clean way to compare a variable against multiple possible values, instead of using several repetitive {% if %} conditionals.

Take this template for example, which is running different template code depending on a Matrix block’s type:

{% if matrixBlock.type == "text" %}

    {{ matrixBlock.textField|markdown }}

{% elseif matrixBlock.type == "image" %}

    {{ matrixBlock.image[0].getImg() }}

{% else %}

    <p>A font walks into a bar.</p>
    <p>The bartender says, “Hey, we don’t serve your type in here!”</p>

{% endif %}

Since all of the conditionals are evaluating the same thing – matrixBlock.type – we can simplify that code using a {% switch %} tag instead:

{% switch matrixBlock.type %}

    {% case "text" %}

        {{ matrixBlock.textField | markdown }}

    {% case "image" %}

        {{ matrixBlock.image[0].getImg() }}

    {% default %}

        <p>A font walks into a bar.</p>
        <p>The bartender says, “Hey, we don’t serve your type in here!”</p>

{% endswitch %}

If you’re using the {% switch %} tag inside of a {% for %} loop, you won’t be able to access Twig’s loop variable directly inside of the {% switch %} tag. Instead, you can access it like so:

{% for matrixBlock in entry.matrixField %}
    {% set loopIndex = loop.index %}

    {% switch matrixBlock.type %}

        {% case "text" %}

            Loop #{{ loopIndex }}

    {% endswitch %}
{% endfor %}

This tag is a bit simpler than other languages’ switch implementations you may have seen: matching cases are automatically broken out of, so there’s no need for break statements.
